Question

the ancient greeks had certain ideas about force and motion. compare and contrast their ideas with those of galileo and newton. cite examples from the readings to support your comparison. also cite examples from what you may already know. type your answer in the box below.

Explanation:

The ancient Greeks, like Aristotle, believed that a force was required to keep an object in motion. For example, they thought that a projectile needed a continuous push to stay aloft. Galileo challenged this view by demonstrating through experiments (such as those with inclined planes) that objects in motion tend to stay in motion in the absence of a net - force. Newton built on Galileo's work and formulated his first law of motion (the law of inertia), stating that an object at rest stays at rest and an object in motion stays in motion with a constant velocity unless acted upon by an external force. For instance, a ball rolling on a friction - less surface would continue to roll indefinitely according to Newton's first law, which contradicts the Greek idea that it would stop without a continuous push.

Answer:

The ancient Greeks believed a continuous force was needed for motion. Galileo showed objects in motion tend to stay in motion without a continuous force. Newton's first law formalized this concept of inertia, stating objects maintain their state of motion without an external force. Examples include Greek ideas about projectiles needing a continuous push, Galileo's inclined - plane experiments, and Newton's law - based scenarios like a ball on a friction - less surface.
